Outlook email worked find with old NIS. Since installing NIS 2012 I have been rebooting several times a day to read my email. One of my two configured accounts works fine. The other remains in 'receiving mail from... state indefinitely without ever receiving mail. Restarting Outlook does not help. Disabling NIS Smart firewall does not help. After a reboot I can get my mail but the next time I try it remains in 'receiving mail from <same account>' indefinitely.
The only permanent (? - it seems to have been working for a while now...) solution has been to disable the NIS AntiSpam addon in Outlook, but that is not an acceptable long-term solution.
